The study patients had a higher protein intake than recommended by ISPAD. Dietary carbohydrate intake was rather low, and dietary fat intake was the same as the limits recommended by ISPAD. Diabetic control was significantly correlated with protein, carbohydrates, fat, and sodium intake. The girls in the study had a higher percentage of body fat than the standard recommendations for their age. The level of physical activity was adequate.

Patients with T1DM had a normal mean BMD at all sites evaluated, except for two patients who had low BMD at the lumbar spine. More than 95% of patients had insufficient or deficient vitamin D levels. With respect to all the variables studied, serum calcium presented the highest significant correlation with LS2-LS4 BMD.

Método: Estudio cualitativo y exploratorio, basado en la Teoría del Comportamiento Planeado realizado a partir de 3 grupos focales (n= 25). La información se analizó con la técnica Análisis Temático a partir de tres categorías definidas a priori: creencias conductuales, normativas y de control. Resultados: Los universitarios creen que alimentarse de manera saludable beneficia la salud física y mental, dentro de las desventajas de este tipo de alimentación se encuentra que la compra y preparación de alimentos saludables es más costosa y les toma mucho más tiempo que alimentarse en base a comida rápida. Paralelamente, declaran que implementar una alimentación saludable sería más sencillo si vivieran en familia y sus madres se hicieran cargo (creencias de control). Con respecto a las creencias normativas, señalaron que sus figuras parentales serían más felices si los participantes se alimentaran sanamente, pero que en lo concreto, no sienten ninguna presión social por alimentarse adecuadamente. Conclusión: Las características poco saludables de la conducta alimentaria de los universitarios, está condicionada por las creencias que subyacen a ella. Al profundizar en estas creencias se puede comprender la perspectiva del estudiante frente a su alimentación, siendo esta información clave y contextualizada para diseñar intervenciones efectivas en las universidades.

Introduction:In children with celiac disease, gluten intake causes an autoimmune, inflammatory and progressive lesion of the small intestine villi, compromising the absorption of nutrients and possible damage to others organs. Objective: To determine plasma 25-hydroxyvitamin D [25(OH)D] concentrations in Chilean child and adolescents with celiac disease. Patients and Method: A descriptive cross-sectional study was carried out in which 16 pediatric patients of both genders diagnosed with celiac disease participated. General background, nutritional status and biochemical parameters were determined. Plasma 25(OH)D concentrations were classified as sufficient between 30-100 ng/ ml, insufficient between 20-30 ng/ml and deficient as <20 ng/ml. Results: The age of the patients was between 5 and 18 years (age: 11 ± 4 years). Four out of 16 participants had normal 25(OH)D concentrations, eight had insufficient concentrations and one had deficient concentrations. According to BMI, 11 patients had normal nutritional status, four were overweight and one was obese. In relation to height, seven out of 16 cases presented short stature and normal-low height. Associating 25(OH)D concentrations to nutritional status, nine patients with normal nutritional status, two with overweight and one with obesity presented deficient and insufficient parameters. No significant associations were found between 25(OH)D concentrations and all studied variables. Conclusion: A high frequency of insufficiency and deficiency of 25(OH)D was found in the group of Chilean children and adolescents with celiac disease.
